Windows DEFRAG command
The Windows defrag command is a built-in tool that helps optimize the performance of your computer by rearranging data on your hard drive. When files are created, deleted, or modified, they become fragmented, scattered across different locations on the disk. This fragmentation can slow down your system as it takes longer to access the scattered pieces of a file. The defrag command works by rearranging these fragmented files, placing them contiguously on the disk, which can improve your computer’s speed and efficiency. Running the defrag command regularly helps maintain the health and performance of your hard drive.
